The John Deere 644B is a wheel loader designed for material handling, loading, stockpiling, and general construction work. As part of John Deere's B-series wheel loaders, the 644B was built for use in aggregate yards, roadbuilding, agriculture, and industrial sites. It features a front-mounted loader bucket, articulated steering, and a diesel powertrain suited to repetitive loading cycles and site transport. The 644B is commonly referenced in used equipment, parts, and service contexts due to its established presence in the wheel loader market. It remains a recognized model for operators seeking a mid-size loader in legacy John Deere equipment listings.
